ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

Application filed May 10, 1917.

attachment adapted to beiconnected with thev carbureterof an internalcombustion engine, by means of which steam and water are drawn from theradiator of the-engine and delivered into said carburetor in asuperheated condition by action of the heat radiated from the exhaust ofsaid engine.

Another object of the invention is to pro vide an attachment of thischaracter which when applied-to an internal combustion engine is adaptedto increase the speed or power of the motor, effecting a saving of.

gasoleneand oil, and preventing the deposit of carbon uponthe interiorof the cylinders and other parts thereby keeping the spark plugs andvalves free from obstruction.

A still further object of the invention is to provide a simple andcompact attachment of this ';-character readily. applicable to varioustypes-of internal combustion engines, which isfadapted to utilizetheheatradiated from the .exhaust pipe to perform the super-heatingfunction.

A still further objectof the inventionis toprovide a device ofthischaracter which is easily andsimply constructed, inexpensive tomanufacture, and one which willbe very eliicientyin, operation.

W'ith these and numerous other objects in view my invention consistiofthe novelfeatures of construction, combination, and arrangement of,parts which will be herein referred to, and more particularly pointedout in the specification and claims.v

form of the super-heating chamber applied to the exhaust pipe.

In describing my invention I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views. InFig. 1 I have shown the device attached to theconventional form of the exhaust manifold 1 of an internal combustionengine, the intake manifold being represented at 2 and associated with aconventional type of carburetor 3, these various parts being of the typegenerally used in internal combustion en gines.v The parts aboveenumerated form the parts to which the attachment is connected and withwhich it is associated to carry. out the function to be hereinafter morefully described. i I

The numeral 4 designates a jacket of any desired shape, preferablycylindrical as shown in the accompanyingdrawings, and.

surrounding a portion of the exhaust pipe 1. This jacket is spaced fromthe wall of the pipe 1, as clearly shown in Fig. 2 of the drawings.Positioned within a jacket is the super-heating chamber 5, which isconnected by a pipe v6 extending upwardly through the jacket 4- andadapted to be connected into the top of the radiator which is associatedwith internal combustion engines. radiator is not shown, the same beingof the conventional type ordinarily usedin devicesof this character. Thejacket t is connected with the carburetor 3 by. means of a pipe 7, saidpipebeing adapted to be formed in any desired shape, accordingto thetype of engine to which the device is applied,.in some instances itbeing necessary, tomake the same flexible;

,The preferred type of super-heating chamber employed in this inventionconsists ctheexhaust. pipe, and. to be; positioned on the same as,clearlyshown in'F-ig; 2 of the with a pair ofvehtpipes 9 thatextent fromone end at the lowest point as clearly shown in Fig, 3, the said pipesbeing adapted to The carry off any unvaporized water from said chamber.The pipes 9 extend through one end of the jacket 4, and are carried toany suitable point for dischargingthe water.

In Fig. l. is shown a slightly modified form of super-heating chamberwhich is designated by the numeral 10, the same comprising a zigzag pipeextending across the portion of the exhaust pipe 1 which is inclosed bythe jacket 4, said pipe having a plurality of spaced perforations 11through which steam is adapted to escape into the jacket. The pipeextends through one end of the casing to carry off the unvaporizedwater, the other end of said pipe being connected with the pipe v6 whichextends to the radiator of the engine.

'- In operation, it is obvious that the steam and water will be carriedfrom the topof the radiator or fromthe water tank, through a the pipe '6t0 the super-heating chamber 5. In this "chamber the vapor will besuperheated and the steam will beforced throughthe perforations 8, or'11 accordpipe 7 to the carbureter 3.

ment is very simple, and may be econ0mi-' rally: constructed, and owingto its ex,-

ing to the form used, into the interiorof the jacket 4. From the jacket4:, the superheated vapor is carried througl i the outlet hisattachtreme simplicity, the same is applicable to various types ofinternal combustion enthe 4 may gines, with practically no change to thestructure thereof. The

attachment will greatly increase the efliciencyvor durability of theengine,:as it will effect a saving of' asolene and oil, and removecarbon from interior of the cylinders thereby keeping the spark plugsand valves clear of,

the deposit of carbon. The pipe 10 in Fig. extend longitudinally in thejacket 4 if so desired From the foregoing description, taken in'connection with the accompanying drawings, the advantages of theconstruction and of the method of operation Wlll be readily apparent to:those skilled in the art I i to which the invention appertains,

whileI have described the principle of op eration of the invention,together with the device which I now consider to be-the best embodimentthereof, I desire to have it understood that. the device shown is merelyillustrative, and that such changes may be iiia'de. when desired as arewithin the scope oftth'e claims appended hereto.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

1. In combination with the exhaust manifold. of an internal combustionengine, of

a jacket entirely surrounding the exhaust manifold and closedat the endsand adapted to communicate with the carbureter, an arcuate chamberwithin the jacket and bearing at one side upon the exhaust manifold andwith the other side perforated and spaced from the jacket, and an intakecommunicating with the chamber.

2. The combination with an internal combustion engine includingtheexhaust manifold and the carbureter, of a jacket entirely surroundingthe exhaust manifold and closed at the ends and communicating with thecarbureter, an arcuate distributing chamber within the jacket andbearing at ;one side upon the exhaust manifold and spaced at the otherside 'from the jacket, the spaced side of the chamber being perforated,and an intake'communicating with the chamber.
